Hear me out here - this may seem crazy, and maybe they’ve worked with him on this, but I almost feel like he should practice his free throws with just his right hand. It seemed to me whatever he is doing with that hitch would not be possible without the left hand on the ball. It’s only supposed to be there to somewhat guide the ball anyway, right? Obviously I wouldn’t expect him to shoot with just one hand, but maybe that would get his muscle memory back to a good place. Just spitballing here. It’s painful to watch and I feel bad for him.
